Dehumidifier powers on but compressor never starts; fan runs continuously and no water is collected.

Safety: Unplug the unit. Compressor and capacitor work involves potentially dangerous voltages.

Steps:

• Check settings: Ensure the humidity setpoint is lower than the room humidity and that the unit is not in fan-only mode.
• Listen for clicks: When the unit calls for cooling, you should hear a click from the relay and then the compressor hum. Repeated clicking without start suggests a start device issue.
• Access compressor compartment: Remove the rear panel to expose the compressor and its start components.
• Inspect start relay and capacitor: Look for burn marks, melted plastic, or bulging on the capacitor. Replace with Frigidaire-approved parts if damaged.
• Check wiring: Ensure all wires to the compressor terminals, overload, and relay are secure.
• Professional testing: Measuring compressor winding resistance and capacitor values requires a multimeter and experience. If unsure, contact a technician.
